Product Description
The Dell UD558 is a high-performance 146 Gigabyte (GB) 3.5-inch internal hard disk drive (HDD) that utilizes the Ultra320 SCSI interface. This interface provides a maximum transfer rate of 320 Megabytes per second (MB/s), making it suitable for demanding server applications that require fast data access and high throughput. The drive spins at an impressive 15000 revolutions per minute (RPM), which is among the fastest rotational speeds for HDDs, significantly reducing seek times and improving overall I/O performance. This makes it an excellent choice for mission-critical systems, database servers, and high-transaction environments. The UD558 features an 80-pin SCA (Single Connector Attachment) interface, which is standard for Ultra320 SCSI drives and supports hot-swapping capabilities in compatible server chassis. Hot-swapping allows drives to be replaced or added without shutting down the system, ensuring continuous operation and minimizing downtime. The 3.5-inch form factor is typical for enterprise-grade drives, offering a robust physical design suitable for server environments. Engineered for reliability and sustained performance, the Dell UD558 is built to withstand the rigors of 24/7 operation. Its combination of high rotational speed, advanced SCSI interface, and robust construction makes it a powerful storage solution for servers and workstations that need to handle intensive workloads and provide fast, dependable access to data. The 146GB capacity is optimized for performance-critical applications where speed is prioritized over sheer storage volume.
